This invention is intended to provide an 'improved piling or coller-damwall construewhile ramming into place,'which gives rise to muchdinieulty 'and delay in assembling them'properly in a Wall construction.Even a rigid -connection :together by interlocking union or jointlocking bars to form a channel design does not always prevent thespringing open' of the joints and 1t is almost impos- .sible to attain areally rigid jointure ofad A like.

jacent members in place, due to the strain from necessary rammin g, evenif they are put together in united pairs.

T he present invention aords a remedy in that those jointing. memberswhich, on account of the ramming cannot be rigidly connected togetherbutmay only be slipped one into the other, are so connected by means ofan intermediate member that springing open is precluded 'even under themaximumstrains.` imposed.

Two practicable embodiments of .the invention are illustrated in crosssection by the attached drawings., in which Fig. 1. represents one formand Fig. 2 another.Y

4Fig.- 1 shows two Z-shaped sheet-piling members a and b connectedtogether by a locking member c and also rigidly connected at the joints'(Z by pressing, welding or the The-members a .and Z) are each formedwith'bulbous edges c along the sides which are connected together bysaid member c, but they differ from each other in that Whereas one (b)has a similar edge Z at its opposite side, the other (a has a claw orsocketedge atthe opposite s1 e, providing for uniting to aduplicate ofsaid one on the opposite side vof the middle plane of the two.

The aforesaid member a is slipped over the bulbous edges of these pilingmembers (a and b) and is formed with two integrally connected clawswliichfo'ppositely extend substantially andv closely over the angeportions thereof so as entirely to prevent the joint from springingopen, even under the application of the greatest forces. 4A furthersecurity against opening can be provided, according to Fig. 2, whereinthe ends of thc tlangeportions of the pilingmembers a and I) connectedby a corresponding intermediate member c are shown formed with abutmentribs or tongues f alongtheir edges', which engage the outer edges of theclaw parts of said connecting member.

Obviously the joints could be designed to enable the outer surfaces ofthe Z-sections to lie flush with one another, so as to present a levelsurface for the attachment of. strnctural members, such as channel-ironanchors. e5 The joints could also be locked together without anyintermediate members if made of suicient lthickness. This affords theadvantage that those edges of the Z-sections which are to be unitedby-pressing, welding 7o or the like may be of slender construction, onlythose edges of the channels formed which connect withl adjacent membersbeing made stouter.'

Having now particularly described and ascertained the nature of my saidinvention and in whatv manner the same is to be performed, lv declarethat what I claim is A 1. A sheet-piling wall of Z-shaped sectionmembers assembled in channel forming relaso tion with ri 'd jointure inpairs at one side and interloc ing'conn'ections at the other; saidconnections comprising double-end deepsocketed plate membersinto whichbulbous edges` of the same slidably fit with the bifurcated'portions ofsaid members extending substantially and closely over the fiangeportions or margins thereof in a virtually rigid joint. A

2. A sheet-piling Wall according to claim 1, wherein the flange portionsof the section members are formed with ribs on opposite surfacesengaging over the outer ends of the plate members connecting the sametogether.

3. A sheet-piling wall comprising Z-shaped section members havingbulbous Side edgesY and double-end socketed plate members1ntereonnecting the same in channel-forming relation; said plate membersbeing slidably engaged over the marginal portions of said 100 sectionmembers with the bulbous edges of the same deep seated therein and withthe ends thereof substantially and closely embracing their saidportions.

4. A sheet-piling wall comprising Z S-shaped section members havinulbous side edges rigidly united at one side of the wall in achannel-form assembly, and doubleend socketed plate membersinterconnecting the same at the other side of the wall; said platemembers being ,slidably engaged over the opposin marginal ortions ofadjacent section mem erswithV t e bulbous edges of the same dee seatedtherein and with their ends substantially and closely embracing saidmarginal portions ofthe section members so as to provide a substantiallyrigid connection therebetween.

5. A sheet-piling wall according to claim 4, wherein the mar nal ortionsof the section members are orme with longitudinal ribs on op osite sideswhich engage against the ends o the plate members in a vice-likerelation.

In testimony whereof I aix my si KARL NO y ature.
